Has nothing to do with the technology and everything to do with the sales. It has everything to do with the COST of the technology tho. Basically the problem is battery cost vs price. These things are rich man's toys. If saving money is your objective, buy a Cruze and put the left over $20,000-30,000 toward gas. I understand the government will subsidize your electric car purchase to make that price delta look more attractive but that does not reduce the cost, it only transfers it to people who can't afford to buy one. ----------------------------------- Very true. Look at the subsidy for a Tesla. Average income of a Tesla buyer? $250k. As to technology. In 1919 an electric car got 30 miles to the charge. What does a Volt get? 30 miles. Not a lot of technology improvement in nearly a 100 years. Still down to battery technology. Plus where is the power to charge going to come from? They say no pollution. What about that coal or oil fired generating plant? Actually they had a range of about 100 miles, but you'd probably bitch about the 20 mph top speed, the eisenglass windows, and no gasoline backup. It appears that the same problems they were having 100 years ago with electric vehicles are the same problems they have today. http://inventors.about.com/od/estart...c-Vehicles.htm The initiation of mass production of internal combustion engine vehicles by Henry Ford made these vehicles widely available and affordable in the $500 to $1,000 price range. By contrast, the price of the less efficiently produced electric vehicles continued to rise. In 1912, an electric roadster sold for $1,750, while a gasoline car sold for $650. I'm waiting on the fuel cell. You people talk like the Wright Brothers were idiots for not building the 747, first. Maybe Edison should have invented the halogen bulb, first. You will notice that the Wright brothers plane runs on the same fuel that today's 747 runs on. I don't know where you came up with that gem of misinformation, but it is demonstrably totally wrong. (Like the rest of your assertions.) The response you'll type to this will be possible because of all of the money spent 50+ years ago on the space program, which a lot of people said was idiotic and useless. http://en.wikipedia.org/wiki/History_of_the_Internet Things change and the gas station as we know it is on the same path as the blacksmith at the end of the 19th century. The fueling station will not change for another 50 years. You will soon be proven wrong. Look for LPG light trucks and cars in the next model year or so, with road tractors soon to follow. It will be a small leap to add electrical power. http://www.extraordinaryroadtrip.org/research- library/technology/liqufied-petroleum/ad-draw.asp The drawbacks of LPG include: In cold conditions, below 32 degrees Fahrenheit, starting could be a problem because of the low vapor pressure of propane at low temperatures. One gallon of LPG contains less energy than a gallon of gasoline. The driving range of a propane vehicle is about 14 percent lower than a comparable gasoline-powered vehicle. LPG is generally higher priced than other fuel alternatives such as CNG and gasoline. There are over 4,000 LPG refueling sites in the US, more than all of the other alternative fuels combined. Most of these stations, however, are not readily available to consumers on a 24/7 basis. This is one of the reasons why most on-road applications are bi-fuel vehicles, which burn LPG and gasoline. http://en.wikipedia.org/wiki/File:Energy_density.svg You will notice that the Lion battery is way down near 0,0. The Lion battery's days are numbered. Better technology is just around the corner. They are working on the heat problem. They haven't come up with anything better, NiMh isn't any better. The plastic batteries are not ready for prime time. And the ceramic batteries are not cost effective to manufacture. LPG is NOT higher priced than gasoline. By what measure? Cost. Cost per gallon? Cost per pound? Engineers are supposed to be precise and un ambiguous. So far you ain't doin so good. Does it matter? Considering the current respective costs, cheaper is cheaper. At this time it is cheaper per gallon. At this time it is cheaper per pound. At this time it is cheaper in cost per distance covered. At this time it is cheaper in BTU consumed. It is cheaper to use as a fuel. ---------------------------------------- Cost per MPG? LPG is about $3+ around here. $3 ? It costs $60 to fill a 20# grill tank? Holy crap! I can get one filled, retail, for a little over $14.00, including tax. I buy 33# for about the same price including tax, delivered. (This company won't do consumer tanks.) Who knows what the stuff really costs? And what the markup is. ----------------------------- You seemed to be Math challenged. $3 a gallon is not $3 a pound. Around here the tank exchange is about $18 and they are not full fill. Where is the benefit of tank exchange when propane stations seem to be everywhere? The EPA makes it difficult for new distributors to put above ground tanks, and filling stations have lots of other regulations... But almost any retailer can make room for a locked 10x10 foot cage with ready to go, filled tanks... I like the convenience of having the attendant thae the tank out of my trunk, fill it, and put it back, * full*. -- O M G |
